You can save on fertilizers

The declining soil fertility, changing weather patterns and soaring prices of agricultural inputs such as fertilizers pose a serious problem to resourcepoor small-scale farmers. In several issues, The Organic Farmer has published tips on how to build soil fertility through the use of well-prepared compost, crop rotation and planting of nitrogen fixing legumes. Page 3

70 percent of Kenya’s total energy demand is met by wood fuel and charcoal. The pressure on our forests for firewood and charcoal has speeded up severe deforestation. This will lead to the destruction of so many water catchment areas and in the long term , cause the drying- out of agricultural

Cost effective-technology One possible alternative to firewood especially for farmers is the installation of a biogas unit using the tubular Polythene (plastic) Biogas Digester. It is an efficient and a cost-effective technology. The costs for a biogas digester made from polythene tube vary, but for a 2-cow unit, one can spend between Ksh 5,000 and Ksh 8,000. It lasts for about four to five years, if well maintained. Findings at KARI-Embu have shown that the Polythene Biogas Digester fed with dung from two dairy cows can supply 30 to 50% of the total energy needs of a typical rural household of about 5 to 8 people, with up to 60% saving on wood fuel, which is a substantial saving on costs.

A big hurdle facing small-scale farmers in Kenya is lack of small-scale technology that would make their work easier. Simple machines could help them save on time that in turn could be invested in efforts for adding value to farm produce. A motorised machine for example would be an ideal tool for chopping the hard maize stalks or Napier grass to make feed for livestock! Of course, we know about the plight of low income small-holders; when they make some money, a lot of it is spent on other pressing needs such as paying school fees, medical bills, and other incidental expenses. Consequently there is not much remaining that can be ploughed back into the farm after the payment of these bills. Apart from the high costs of transport to remote areas, small-scale farmers in rural Kenya have to cope with many other problems: • Lack of power: Rural electrification programme is crawling at a snail’s pace. This is unfortunate, since most of the small machines that use electrical power are cheaper than those that run on fuel. • Lack of appropriate technology: Compared to the technology used on big farms, develoment of small-scale technology is slow. Good looking designs is one shortfall, its applicability another. • Lack of information: Extension officers know little about small-scale technology. • Lack of interest in new technology: Very few farmers are unwilling to try out something new. However, we know that small-scale farming is a challenging business. Farmers can hardly risk losses. But if they evaluated carefully and took appropriate measures, they could, in the long term, win. Let’s take the example of biogas; it could replace firewood as the only source of fuel in rural households. In this issue, we feature a simple biogas unit which costs around Ksh 5,000 and which has been used by farmers for many years in many developing countries. There is quite a number of cheap small-scale technology equipment which farmers (or farmers’ groups) could use to make work easier, to save time and money, or to expand in value addition of their products. The biogas unit we are writing about in this magazine is only one of them, others are oil presses or solar dryers. Small-scale farming is a business, and farmers should use every chance to boost their income.
